I'm not a Windows user, but I'd probably suggest trying https://www.enthought.com/products/canopy/ (formerly the enthought python distribution EPD) for a relatively hassle-free setup with numpy and other scientific packages. It also works on linux and mac, but I usually go with repository versions on linux.

Other comments suggest https://store.continuum.io/cshop/anaconda which I haven't tried to compare, but also looks promising.
